Aura strong transmutation; CL 17th
Slot shield; Price 50,170 gp; Weight 15 lbs.
This +1 heavy steel shield is made of metal, but its color is flat black that seems to absorb light. Once every 2 days, on command, it can disintegrate an object that it touches, as the spell but requiring a melee touch attack. This effect only functions as an attack—it can't be activated to target a creature or weapon as it strikes the shield.
Requirements Craft Magic Arms and Armor, disintegrate; Cost 25,170 gp
